Elastic Search Pluggable REST End point (POST)

Prasanna_Paulraj · December 12, 2012, 6:52pm

Hi All,

I am new to elastic search and I am trying to develop a pluggable rest end
point. Can some one point me to some tutorial or info on how to work with
POST request. I got some examples but they are for GET request. Couldn't
find any thing for POST.

Thanks,
Prasanna

Both Jörg Prante and I have written tutorials on the subject.

Tutorial:

Code: GitHub - brusic/elasticsearch-hello-world-plugin: Tutorial on how to create a new REST endpoint in elasticsearch

Tutorial:
http://jprante.github.com/lessons/2012/03/27/Writing-a-simple-plugin-for-Elasticsearch.html
Code: GitHub - jprante/elasticsearch-index-termlist: Elasticsearch Index Termlist

The Action class, which is bound to the RestModule via the plugin, will
register various action with the rest controller. Using my code as an
example:

github.com

brusic/elasticsearch-hello-world-plugin/blob/master/src/main/java/org/elasticsearch/rest/action/helloworld/HelloWorldAction.java

package org.elasticsearch.rest.action.helloworld;

import org.elasticsearch.action.ActionListener;
import org.elasticsearch.action.get.GetField;
import org.elasticsearch.action.get.GetRequest;
import org.elasticsearch.action.get.GetResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.common.Strings;
import org.elasticsearch.common.inject.Inject;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.xcontent.XContentBuilder;
import org.elasticsearch.common.xcontent.XContentBuilderString;
import org.elasticsearch.rest.*;

import java.io.IOException;

import static org.elasticsearch.rest.RestRequest.Method.GET;
import static org.elasticsearch.rest.RestStatus.NOT_FOUND;
import static org.elasticsearch.rest.RestStatus.OK;
import static org.elasticsearch.rest.action.support.RestXContentBuilder.restContentBuilder;

This file has been truncated. show original

controller.registerHandler(GET, "/_hello/", this);
controller.registerHandler(GET, "/_hello/{name}", this);

You would need to simply define these as POST and not GET.

Hope this helps,

Ivan

Hei,

I'm also trying to write a custom plugin , which can also be called straight from java with a transport client. My plugin only needs to use existing features like search, analyze ( I'm building it in order to go less to es and do everything on the server side ).

In the BaseRestHandler class I can easily access the client. But when I'm trying to build the hierarchy for the java execution ( action, request, response, builder ) I don't have access to a client which exposes to me all these actions.
It's not clear to me which base classes should I extend in order to be able to use it. Also, I don't need to do something specific for each shard, I would like the client to handle everything.

Is it possible to do this ? Can you please point me in the right direction because I've been struggling with this for days now.

Thanks,
Alexandra
